Hi,I Have Been Using Microgynon 30 For The Last Three

Hi,I have been using Microgynon 30 for the last three months and I am finishing my pack in two days.As I am abroad ,I haven't found Mycrogynon 30 but Microgynon 30 ED.I have been told the same but my question is :
Should I have that seven day break and then start Microgynon 30 ED or should I start the next day I finish my Microgynon 30 pack.Thanks for answering and looking forward to a prompt reply.
